#
# Submitted:
#
# Dimitry Andric <dimitry@andric.com>, 2004-05-01
#
# Description:
#
# Nicholas Pitre released this patch for gcc soft-float support here:
# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
#
# This version has been adapted to work with gcc 3.4.0.
#
# The original patch doesn't distinguish between softfpa and softvfp modes
# in the way Nicholas Pitre probably meant. His description is:
#
# "Default is to use APCS-32 mode with soft-vfp. The old Linux default for
# floats can be achieved with -mhard-float or with the configure
# --with-float=hard option. If -msoft-float or --with-float=soft is used then
# software float support will be used just like the default but with the legacy
# big endian word ordering for double float representation instead."
#
# Which means the following:
#
# * If you compile without -mhard-float or -msoft-float, you should get
# software floating point, using the VFP format. The produced object file
# should have these flags in its header:
#
# private flags = 600: [APCS-32] [VFP float format] [software FP]
#
# * If you compile with -mhard-float, you should get hardware floating point,
# which always uses the FPA format. Object file header flags should be:
#
# private flags = 0: [APCS-32] [FPA float format]
#
# * If you compile with -msoft-float, you should get software floating point,
# using the FPA format. This is done for compatibility reasons with many
# existing distributions. Object file header flags should be:
#
# private flags = 200: [APCS-32] [FPA float format] [software FP]
#
# The original patch from Nicholas Pitre contained the following constructs:
#
# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
# %{mhard-float:-mfpu=fpa} \
# %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
#
# However, gcc doesn't accept this ";:" notation, used in the 3rd line. This
# is probably the reason Robert Schwebel modified it to:
#
# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
# %{mhard-float:-mfpu=fpa} \
# %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
#
# But this causes the following behaviour:
#
# * If you compile without -mhard-float or -msoft-float, the compiler generates
# software floating point instructions, but *nothing* is passed to the
# assembler, which results in an object file which has flags:
#
# private flags = 0: [APCS-32] [FPA float format]
#
# This is not correct!
#
# * If you compile with -mhard-float, the compiler generates hardware floating
# point instructions, and passes "-mfpu=fpa" to the assembler, which results
# in an object file which has the same flags as in the previous item, but now
# those *are* correct.
#
# * If you compile with -msoft-float, the compiler generates software floating
# point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
# order) to the assembler, which results in an object file with flags:
#
# private flags = 600: [APCS-32] [VFP float format] [software FP]
#
# This is not correct, because the last "-mfpu=" option on the assembler
# command line determines the actual FPU convention used (which should be FPA
# in this case).
#
# Therefore, I modified this patch to get the desired behaviour. Every
# instance of the notation:
#
# %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
#
# was changed to:
#
# %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}

# I also did the following:
#
# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
# be consistent with Nicholas' original patch.
# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
# macros I could find. I think that if you compile without any options, you
# would like to get the defaults. :)
# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
# anymore. (The required functions are now in libgcc.)
